METER.

SPECIFICATION forming part of Letters Patent No. 233,446, dated etober 19, 1880.

Application filet] J anuary 9, 1880.

A nv- T0 all whom z't may concem:

Be it known that we, JOHN H. SWARTZ and DE WITT O. TAYLOR, of the city of Brooklyn, county of Kings, and State of N ew York, have invented a new and Improved Water-Meter.

of which the following is a specification.

Our invention relates to improvements on the rotary water-meter for which Letters Patent No. 197,949 were granted to John H.

[0 Swartz, December 11, 1877.

The object of onr invention is to improve the construction and operation of the inletpipe and the direction-plate; also, to provide an exit to the meter for the leakage in the inlet-pipe when the valve is closed, so that the leakage can be measured, withont, however, permitting the flow et auxiliary streams when the valve is open.

A further object of our invention is to tard just the leverage of the registering mechanism to the pressure of the water.

Other objects of our invention Will be referred to in the description of the several parts of the invention and their operation.

In the accompanying drawings, Figure 1 is a horizontal section of our improved watermeter, taken on line 0 0 of Fig. 2. Fig. 2 is a vertical longitudinal section, taken on line 75 76 of Fig. Fig. 3 is a perspective view of the 0 inlet-pipe and valve, and Fig. 4 is an end clevation of the entrance-port.

Referring to the drawings, Arepresents the lower part of the meterbox; B, the upper part of the same. 0 is the registering meeh- 3 5 anism. D is the entrance port. D is the exit -port, and a is the glass face through which the register is read. E represents the inlet-pipe, which is provided with a circular flan ge, I). The inlet-pipe is inserted in the port 0 D, so that its triangular open inner end, with its valve (1, projects just within the valve-box A, while the collar or fiange b bears against the end of the port D and holds theinlet-pipe immovable within the said port, pins 8 pro- 5 jecting through holes in the flange b to prevent the pipe E from turning. A cap, F, is screwed over the end of the port and against the flange b, to fasten the inlet-pipe in the front, and the outer end of this cap is provided With a screw-threaded socket for the connection of the supply-pipe.

One side, 6, of the entrance-port is straight, so as to serve as a guide for inserting the inlet-pipe, the straight side being on the s1de of the hinged end of the valve. 5

A rod, G, extends from the valve d, through the cross-bar at the outerend of the inlet-pipe, and around this rod G the spiral spring 6 is wrapped, which holds the valve shut. By pushing on the end of the rod the valve can be opened withont removing the inlet-pipe to clean ont, inspect, or repair the 1neter. The npper end of the valve is provided With a notch,f. Through this notch, whenthe water is shut ot', any leakage from the supply-pipe into the inlet-pipe escapes into the meter, and is measured in the same way as the waterthat passes through when the valve is open. By having the notchjin the valve it does not affect the passage of the water from the inletpipe, as it Would were the opening for the passage of the leakage in the inlet-pipe itselt, in which case a definite stream would pass from the inlet pipe in addition to that passlng through the valve-opening, whereas it is nec- 7 5 essary to the properworking of the meter that all the water should pass through the valveopening, so that the size of the exit can be adapted (by the opening and closing of the valve under the influence of the pressure of the water and the restraint of the spring) to the pressure of the water.

The notch or opening f, in addition to providing an exit for the leakage into the meter, also supplies an opening for the back flow of the water from the distributing-pipes and the meter to the water-pipes, when the watersupply is shut off, thereby permitting the water to escape and preventing freezing in the pipes. 0

9 is a plate pivoted to the outside of the valve, which is adapted to be turned so as to partially or entirely close the notch f, and thereby regulate the exit of the leakage from the inlet-pipe. 95

H is the direction-plate. It has its fixed end attached to the inlet-pipe, instead of the meter-body, as heretofore, while its free and projects o"er and beyond the swinging end of the valve (1. By attaching the direction-plate to the inlet-pipe it is made removable therewith, and brought closer to the valve-opening when the water is passing through, whereby the water ejected from the inIet-pipe in a small stream comes more qnickly in contact with the direction-plate, and is deflected down upon the wings of the registering apparatus.

h is the set-screw or other regulator for adjusting the angle of the direction-plate. lts outer end is confined within a box, 1', provided with a serew-cap, j.

h is the sebscrew for regulating the opening of the valve d. The outer end of the setscrew h is confined in a similar box, 1', provided with a similar cap, j. The object of the boxes and caps is to prevent leakage from the valve by the passage of the water around the set-screws. As the boxes will, in case of leakage, fill with water in a short time, a waterpacking will be provided which will preventa further waste ot water from the same source.

The object of the regulator h is to limit the possible opening of the valve (1, and thcreby, also, the direction and speed of the issuing stream.

The wings I lare held on the anus l l of the shafL of the registering apparatns by e ves m and set-screws n. This permits the said wings to be adjusted to and from the central shaft, and thereby increase or decrease their leverage, so that the leverage tl1ey exert on the registering apparatus can be adjusted to the pressure of the water passing through the meter.

K is a thimble-shaped screen or sieve, which is placed over the outer end of the inlet-pipe to prevent the entrance of fisb and solid matters of any kind into the inlet-pipe and meter. The spring-rod passes freely through this sieve, as shown.

The stop h in the mater-box serves also as a means of giving direction to the large stream, and thereby to regulate the eflect of the stream upon the registering mechanism of the meter.

We claim 1. The meter-box A, having nlet-port D, which is provided with a straight aide, a, in combination with the removable inlebpipe E, said straight side being adapted to guide and facilitate the insertion of the said inlet-pipe, substantially as described.

2. The guide-rod G, in combination with the valve d, With the spring 0, which surrounds said rod, and with the inlebppe E, the outer end of the rod passing loose through 3. guidepiece in the inlet-pipe, the inner end ot said rod, and also that of the spring, being directly connected with said valve, substantially as specified.

3. The pivoted plate 9, in combination With the valve (1, provided with the noteh f, sub stantially as described.

4. In combination with the plate H and setscrew h, the box 2, provided wth the screwcap j, as and for the purpose substantially as described.

5. The meter-wings I, adjustable on the arma I, in combination with the registering mechanism C and inlebpipe E, substantially as described.

6. In a water-mcter, the combination of the inletpipe E, direction-plate H, meter-box A, and wiugs with the adjustable stop h, and with the hinged valve d, all arranged to opera-te suhstantially as herein shown and described.
